Where Do Frogs Sleep? Understanding How and Where Frogs Sleep

Where do frogs sleep?

Frogs are often seen around ponds, rivers, and streams. They are nocturnal creatures which means they sleep during the day and come out to play at night. But where do frogs actually sleep? 

Frogs usually have two types of sleeping places: hibernation spots or dry land homes. Hibernation spots can be found in logs, burrows, hollow trees or even under rocks that protect predators like snakes. Dryland homes include bushes, weeds or grassy areas near water sources.

If you’re curious about where frogs sleep and other behaviors of these unique creatures, this blog post shares some fascinating facts you’ll love to read! So, let’s jump right in. Shall we?

How Do Frogs Sleep?

The topic of frog sleep is a fascinating one. However, interestingly, there’s little research on the topic of frog sleep habits. For a long time, scientists believed that frogs didn’t sleep at all. However, recent studies have shared some interesting facts about when and where frogs sleep.

So, do frogs sleep? Yes. However, it’s not the kind of sleep that mammals like humans are known to experience. You see, frogs employ what is known as a Slow-Wave sleep pattern, also known as Non-REM Sleep or Quiet Sleep. Furthermore, typically, amphibians are known to display three types of rest known as; primary, catatonic, and cataplectic sleep.

To understand the difference between frog sleep and human sleep, you need to understand the sleep patterns for both. 

Understanding Human Sleep

Human sleep is defined by several factors, including:

  • A period of immobility
  • Rapid Eye Movement (REM)
  • Variation in brain waves
  • Specific brain activity
  • Motor automatisms
  • Muscle atonia
  • Lower metabolic rate
  • Lower brain temperature
  • Slower breathing and heart rate

Humans, birds, and other mammals typically have two types of sleep. These include:

  • Paradoxical sleep: REM sleep, or active sleep
  • Slow-wave sleep: Non-REM sleep, or quiet sleep

In the 1960s, researchers applied the same criteria to frogs and discovered that frogs didn’t necessarily fit into either of these sleep categories. You see, frogs are cold-blooded amphibians. Consequently, they don’t have the same sleep patterns as humans, and other mammals do.

Although these amphibians have a prolonged period of immobility that may be considered sleep-like, they regulate temperature differently and don’t have the same brain structure as humans.

Furthermore, frogs hibernate when winter comes. Their body temperature drops, and they stop moving for long periods until the weather gets warmer. This is something humans don’t experience.

Understanding Frog Sleep

So, if frogs don’t experience the same type of sleep humans do, how can we define frog sleep? Research shows that frogs have three types of rest or sleep-like habits. These include:

  • Primary sleep: Frogs get into this state of rest during the day and keep their eyes open.
  • Catatonic sleep: Happens during the night, and the frog may have rigid muscles.
  • Catapletic sleep: Happens during the night, and the frog may have atonia.

Frogs typically get into intermediate sleep between primary and cataplectic sleep. However, you don’t need to be a scientist to tell when a frog is sleeping. You can tell because their eyes are closed, and they aren’t moving, but this isn’t always the case since sometimes frogs may appear to be awake when really they’re in hibernation or torpor.

Some of the behaviors you should look for include:

  • Immobility for long periods
  • Tucked limbs under the belly
  • Keeping their chin and stomach too close to the ground
  • Covering their eyes with their nictitating membrane

Another difference between human and frog sleep is that frogs can respond to stimuli and predators even when they’re in a resting state. They generally close their third eye (nictitating membrane) so that they can see when danger is approaching.

However, there are over 7000 known frog species and little research on these sleep behaviors. Therefore, there’s a great chance that different frog species behave differently depending on their natural habitats.

When and Where Do Frogs Sleep?

Frogs can sleep in a variety of ways depending on the species and their environment. Tree frogs sleep in trees, aquatic frogs sleep in the water, and terrestrial frogs sleep on the ground while some burrow into the soil.

The climate also influences when and where a frog sleeps. For instance, a frog in a high-altitude cold region will typically hibernate in a den and sleep throughout the winter. As for frogs in hot regions, they will find shade and water to keep cool and stay hydrated by sleeping during the day under vegetation or soaked logs.

Terrestrial Frogs

These are the most diverse species of frogs, and they sleep on land. Toads generally burrow during the day, experiencing prolonged periods of immobility during this time.

These amphibians are mostly active during the night. They can remain immobile for a long time but can instantly respond to food or predators.

Aquatic Frogs

These frogs are mostly nocturnal. They are good at finding hiding spots during the day but must come up for air periodically or risk drowning by staying submerged too long.

These frogs tend to sleep in their watery habitat, often on plants and leaves floating at the surface. When they do go onto land, it is usually only to find more food sources.

Arboreal Frogs

These are grey tree frogs, which are often in sleep-like positions during the day. Normally, these frogs tuck their limbs under their belly with their chin and belly close to the branches.

Where Do Frogs Sleep in a Pond?

Frogs enjoy the water, so most of them are found in ponds. The best place for a frog to sleep is on top of the water’s surface, where it can breathe easily and keep an eye out for predators or prey. Most frogs tend to rest with their eyes open throughout the day but close them at night.

So, where exactly do frogs sleep in the pond? The position depends on the species of the frog and the season. For instance, aquatic frogs hibernate deep under the water during winter. However, it’s not uncommon to find aquatic frogs at the surface of the pond during other seasons.

Some frogs sleep on rocks, leaves, and branches of trees close to the pond’s surface. They prefer sleeping in groups as it is safer this way; they can watch for predators. Some frogs will even build their own nests above water or under fallen logs.

However, generally, most frogs will enter the pond at some point. You see, frogs need to stay moist at all times. If they don’t get enough water in their bodies, they can lose much of it through breathing as it can evaporate too quickly when not submerged in water. 

Do Frogs Sleep In Trees?

There are over 800 species of tree frogs. However, not all tree frogs live in trees. These amphibians are united by one feature —the last bone in their toes (known as the terminal phalanx) is shaped like a claw. These frogs also have toe pads, which help them climb, and most have skeletal structures in their toes. 

Tree frogs can be of any color. However, the majority of species found in the US are grey, green, or brown. Some, like the squirrel tree frog, are chameleon-like in the sense that they can change color.

These frogs can also grow to be a range of sizes. However, most arboreal species don’t grow too big because their diet mainly includes leaves and slender branches.


You can find tree frogs on all continents except Antarctica. However, they’re most diverse in the tropics of the Western Hemisphere. There are about 30 species of tree frogs in the US, and over 600 can be found in South and Central America. Most of these frogs are arboreal, meaning that they live in trees. They vary quite a lot between different species, but most are green or brown with darker spots and stripes to help them blend into the leaves on their home tree branches.

Tree frogs have specialized feet that adhere well to surfaces like smooth rocks or branches. This helps them climb around in search of food and to escape from predators. 

Do Frogs Sleep Through the Winter?

Like all amphibians, frogs are ectothermic. This means that their bodies can’t regulate their own temperatures, so they have to get the energy somewhere else. 

During winter, the temperatures are low, and the frogs head to their winter hibernation spot, which is usually under rocks or logs. They enter a state of torpor where they slow down all bodily processes, including breathing and circulation.

Frogs choose an area where they won’t be disturbed by other animals, and they’ll remain buffered against the extreme cold temperatures. You see, if the frog loses too much water, it will freeze and die. Therefore, it’s crucial that the area is moist and has no freezing temperatures to survive the cold months undisturbed.

Most adult frogs spend winter in ponds or lakes with deep water that doesn’t freeze solid. If the pond ices over, they can survive by staying in their mud burrows below the frost line.

Hibernation ends when the temperatures start to rise again. At this point, the frogs leave their winter homes to look for food and potential mates. They’re very hungry, so they’ll eat anything available, including insects and other small animals.

Wrapping Up

There you have it; everything you need to know about frogs’ sleep patterns and the impact of a changing climate on their lives. As we’ve mentioned, frogs sleep, but their type of sleep is different from humans’. However, you ought to remember that frogs behave differently depending on the species and the climate conditions they live in.

Therefore, if you’re studying a specific species, be sure to research the frog in its natural habitat and the sleep patterns and behavior that are unique to it. Most importantly, remember to enjoy the frog’s antics!
